Hi everyone,
while working with <liferay-ui:form-navigator> (LR7), I noticed a strange behaviour. I created a form with two categories ie name and description.
Under each category I have one section and each section has single input text field. I created jsps for each section. On deploying I found
everything was alright. I had a form as i tried to create.
Then I tried to modify my code and for this I changed the value of form navigator id constant(SAMPLE_FORM_NAVIGATOR_ID) in my constant file. This Constant is being used at all required places(). Again deployed my module, but this time I met with following exception:
10:01:54,456 ERROR [http-nio-8080-exec-8][IncludeTag:128] Current URL /web/guest/home?p_p_id=in_componence_portlet_sample_portlet_SamplePortlet_INSTANCE_Xf9IM5a9uyh7&p_p_lifecycle=0&p_p_state=normal&p_p_mode=view&p_p_col_id=column-1&p_p_col_count=1&_in_componence_portlet_sample_portlet_SamplePortlet_INSTANCE_Xf9IM5a9uyh7_mvcPath=%2Faction-jsps%2Fadd_sample.jsp generates exception: Index: 0, Size: 0

I tried to resolve this but I found that portal is not getting any sections or categories for new form navigaion id value.
Again I replaced the value of form navigaion id constant with the initial value and deployed the plugin. Everything was OK.
I do not know why is it happening? Is this a correct behaviour? Or it is going to be modified sooner ?
Thanks.
